Thanks for the replies so far. Anyone have any links to compnies that sell NIW Springfield Armory XD40 high cap mags? Looks like I'm in the market for a few now. I checked out the SAI site, but if the XD mags have jacked up prices similar to thier M1A 20rd mags, I figure that I should be able to find XD40 mags a little cheaper elsewhere.

Dude, on this point you are fairly well out of luck. The only place that makes a mag over 12 rounds is Pro-Mag. I wouldn't use them for anything but target practice, if even that. Now the New Springfield XDM just came out, it uses a 16 round mag! Unfortunately the XDM mags will not enter the XD magwell
